A rolling device for a device that is to be moved along a surface is described. The rolling device comprises a cylinder with an opening at one end and a piston that is arranged reciprocally movably in the cylinder such that the piston can be moved between an upper position in the cylinder and a lower position in the cylinder. The piston comprises a rolling element that is arranged in a first end portion of the piston that faces the cylinder opening and that rolls on the surface when the device is to be moved. The rolling device further comprises an actuator system for movement of the piston between the upper position and the lower position in the cylinder.

A device for removing obstructions impeding movement of equipment is disclosed. The device includes two panels connected by four axles, each axle rotatably connected to the panels, and two bridges. Two brush assemblieseach having an adaptor, a platform, and a plurality of brushing articlesare connected to the bridges. When a user mounts the device around a caster wheel, obstructions are pushed away from the caster wheel by the one or more bristle implements.

A shock absorber wheel system for absorbing vibrations and impacts on precision transport and the translocation vehicles like patient stretchers, new born baby units, portable medical devices in the health sector has a track wheel, a compressive spiral spring absorbing the vibrations and the impacts, an upper spring holder which is connected to the spiral spring and has a spindle at one end and a centering housing at the other end, a lower spring holder which is connected to the spiral spring and has a housing providing connection to the track wheel at one end and has a centering spindle connected to said centering housing.

A caster for equipment and furniture, the caster comprising a support element including a top element and a base element, wherein the top element includes an attachment bolt configured to attach the caster and the base element includes a wheel axle that supports at least one wheel, wherein a replaceable substantially circumferential one-piece support element cover made from a synthetic material that provides a continuous design surface is arranged at the support element.

A caster may include a shaft, a first elastic ring, a C-shaped ring, and a second elastic ring. The shaft has one end inserted and secured in a wheel, and a first rod is extended from the other end of the shaft, and a second rod protrudes from an end of the first rod. The diameter of the first rod is larger than that of the second rod, and an end of the second rod comprises a flexible portion. The shaft only needs to be processed to form the second rod and the flexible portion, and the first elastic ring and the second elastic ring which are identical are adapted to be formed through the same mold so as to save the manufacturing cost.

A wheel assembly for installation on a shopping cart to retro-fit the shopping cart for facilitating self-checkout. The wheel assembly may include a support structure and a wheel rotatably supported on the support structure. The wheel assembly may further include a rechargeable battery supported by the support structure and a charging module supported on the support structure. In addition, the wheel assembly may include a force-detection module configured to provide a signal related to an item event in which an item is deposited within the shopping cart. Still further, the wheel assembly may include a processing and communications unit configured to receive the signal from the force-detection module. The processing and communications unit may transmit the signal to a device that is separate from the wheel assembly.

An automated guided vehicle (AGV) includes a suspension system for movably coupling wheels of the AGV with its frame. The system includes a rocker pivotally attached to the frame. A drive wheel and casters are mounted to the rocker on opposite sides of the rocker pivot axis so that the drive wheel and the pair of casters move together about the pivot axis in the same rotational direction when the rocker tilts. The system can be employed in a simple and elegant manner to ensure continuous traction between the drive wheel and the ground while protecting the drive unit from overload when the AGV traverses uneven terrain.

A device for removing obstructions impeding movement of equipment is disclosed. The device includes two panels connected by four axles, each axle rotatably connected to the panels, and two bridges. Two brush assemblieseach having an adaptor, a platform, and a plurality of brushing articlesare connected to the bridges. When a user mounts the device around a caster wheel, obstructions are pushed away from the caster wheel by the one or more bristle implements.

The present disclosure relates to a wheel connecting structure and a baby carrier. The wheel connecting structure includes a fixed base, a rotatable base, a rotating shaft and an anti-swing member. The rotatable base is rotatably connected to the fixed base by the rotating shaft. The anti-swing member has an abutting portion. The anti-swing member is arranged on one of the fixed base and the rotatable base, and the abutting portion abuts against the other of the fixed base and the rotatable base. The abutting portion is provided with a lubricating structure.

The present invention relates to a caster, and particularly, to a caster which more smoothly rotates when reversely rotating 180? and effectively supports a weight of an object disposed on the caster to smoothly rotate in reverse without any shaking, wherein the caster has a structure in which a central portion, a connecting part, and a lower body part are sequentially provided under a support plate formed in an upper end portion of the caster, and in particular, a rotating part is mounted between the connecting part and the central portion.
